本文报道了大面积超导体-绝缘体-普通金属-绝缘体-超导体隧道结冷却器的最新研究结果。通过这些器件，我们已经成功地展示了从260 mK到80 mK的电子冷却，在80 mK下的冷却功率为20 pW。目前，我们正致力于在冷却低温探测器方面获得类似的性能。此外，我们提出了最近的成功操作的金属半导体结构与肖特基势垒作为隧道势垒和使用这种结构的可能性，用于片上冷却的结果。
In this paper we report recent results obtained with large area superconductor-insulator-normal metal-insulator-superconductor tunnel junction coolers. With the devices we have successfully demonstrated electronic cooling from 260 mK to 80 mK with a cooling power of 20 pW at 80 mK. At present, we are focusing on obtaining similar performance in cooling cryogenic detectors. Additionally, we present recent results of successful operation of a metalsemiconductor structure with a Schottky barrier acting as the tunnel barrier and the possibility to use this kind of structures for on-chip cooling.
